Was just hovering my TRex 450 SE v2 about 10 feet off the ground and the power just cut out... heli was about 20 feet away. It seemed to be kind of autorotating to the ground when the power slammed back on at about 2 feet... I lost it and crashed

Fortunately no major damage that I can tell, just some new blades, maybe a main shaft.

But anyone have any ideas what to look for? Lipo had about 5 cycles on it and was at 60% when the power cut. Felt like something electrical rather than mechanical.
